Disentangler
Posted: 17 Feb 2022, 09:20
Dear Developers,
I have query related to Disentangler implementation in TeNPy. I can see, one can use the existing disentangler under the subroutine PurificationTEBD, when beta(1/Temp.) evolving the state, looks typically made for one-d model. But If one wants to beta evolve the state using PurificationApplyMPO, can one use existing disentangler to reduce the entanglement of finte beta state. Because for 2 -d models wrapped on cylinder, PurificationApplyMPO is an more accurate method. I wanted to basically use these disentangler for my 2-d model on cylinder with beta evolving the state using PurificationApplyMPO on infinite temperature state with ancilla sites.
Thank you!
